Parity redundancy is widely employed in RAID-structured storage systems to protect against disk failures. However, the small-write problem has been a persistent root cause of the performance bottleneck of such parity-based RAID systems, due to the additional parity update overhead upon each write operation. In this paper, the authors propose a novel RAID architecture, TRIP, based on the conventional parity-based RAID systems. TRIP alleviates the small-write problem by integrating and exploiting the temporal redundancy (i.e., snapshots and logs) that commonly exists in storage systems to protect data from soft errors while boosting write performance.
